Hi all. my brother installed a new door frame on the
back of my garage. pretty good job, really considering
neither of us are carpenters or craftsmen :)
he sprayed the heck out the gaps with expanding foam
insulation. as usual it foamed out of the gaps and
needed to be trimmed. it's a typical brother thing.
I thought he was goona trim it. he thought I was.
it's now bone dry, hard as concrete :rolleyes:
I tried to trim it off in this condition, but it seems to have
bonded with various shims and spacers he put in there.
and they move a little when I knudge too hard with the knife.
are we going to need to re-do the entire mess? if yes,
that is not the end of the world. my question is: WHEN
should one or the other of us have trimmed off the excess?
it seems too set up now, though with a really sharp knife
or some type of saw, I suppose we can manage to trim it.
but when are ya supposed to trim off that excess stuff that oozed out? thanks!!

As soon as its firm is the best time. Normally you don't spray so much in, then no need to trim.
Try using something like a bread knife..the serrated edge allows you to just saw through it.

it's a mess, but it's not the end of the world. it is a door
leading from the back yard into the garage. so a little caulk
and some paint will cover up a multitude of sins. Beer 4U2

Some manufactures will void the warranty if you use foam, most don't recommend it. Expanding foam should never be used. It distorts the frame. Even the non expanding allegedly intended for doors and windows is disliked by some manufacturers. Stuffing gently with insulation is the recommended method.

I didn't catch the expanding foam...I always use the DAPTex Window and Door water cleanup kind. Much better insulation and sealing than FG insulation IMO. But yeah..never use Great Stuff, even the window and door kind can expand too much and it sucks to clean up.
But..since its already done..kinda late now anyway.
